I does not matter. I just make a mini change for the ui/js/novnc/base64.js Also js support a btoa/atob for base64 decode and encode btoa("abcdef") "YWJjZGVm" atob("YWJjZGVm") "abcdef" if encodeURIcomponent is OK, we can use it.

I agree to use encodeURIcomponent() in this case. A small comment for the base64: Modern browsers natively support base64 and expose this feature to javascript. Those browsers are Firefox, Chrome, Safari, Opera and IE10+. We don't have to write base64 algorithms if we don't support IE9. We can just use those functions. alert(btoa("http://1 2/3+?aaa&bb=c")); alert(atob("aHR0cDovLzEgMi8zKz9hYWEmYmI9Yw==")); https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_...
